Horizontal ridges can be a sign of malnutrition, nail injury or Beau's lines
Horizontal ridges, also known as Beau's lines, can be a sign of malnutrition, nail injury, or a more serious medical condition. While ridges in your nails are usually harmless, they can sometimes indicate a vitamin deficiency, such as an iron deficiency, or a medical condition such as diabetes. Beau's lines are deep horizontal ridges that may suggest a serious condition.
Vertical ridges, on the other hand, are often a sign of aging, and are sometimes called longitudinal striations or bands. They commonly develop in older adults due to a slowing of cell turnover. However, if you experience texture changes in your nails along with vertical ridges, it may be caused by a medical condition.
It's important to pay attention to fingernail ridges and other nail changes as they might be the first signs of a serious medical problem. If you notice any unusual changes in your nails, it's always best to consult a healthcare professional for proper diagnosis and treatment.

White spots or streaks are normal and nothing to worry about
White spots or streaks on your nails are usually harmless and nothing to worry about. Vertical ridges, which run from the tip of your fingernail down to the cuticle, are often a sign of ageing, possibly due to a slowing of cell turnover. However, they can also be caused by improper nail care or nail trauma. Horizontal ridges, which are usually deeper than vertical ones, can be a sign of malnutrition, a serious nail injury, or Beau's lines. Beau's lines are often linked to more serious health issues, such as severe infections, diabetes, or nutritional deficiencies.
If you are concerned about the appearance of white spots or streaks on your nails, it is best to consult a doctor or healthcare professional. They can help determine the underlying cause and provide appropriate treatment or advice.
